Quality improvement initiative reduced unnecessary GAS pharyngitis testing, report says
Unnecessary testing for group A streptococcal (GAS) pharyngitis was less common in one ambulatory pediatrics practice after a collaborative interprofessional quality improvement (QI) initiative, results of a study found.
The average monthly frequency of unnecessary testing in that practice fell from 64% before the intervention to 41% afterward. Although the initiative did not appear to improve appropriate antibiotic use for GAS pharyngitis, most of the providers (88%) perceived an improvement in their ability to communicate with families about appropriate antibiotic use and the need for testing, Laura E. Norton, MD, of the University of Minnesota, Minneapolis, and her associates wrote.
The QI project was implemented at a pediatrics practice with two locations in Kansas City, Mo., with 12 board-certified pediatricians, 19 nurses, and 4 certified nurse practitioners who provide care for more than 40,000 children annually. Interventions that were part of this project included education for providers, patients, and families; office procedure modifications;and discussions with providers about communicating with families, along with periodic feedback to providers on improvement in outcomes measures.
Dr. Norton and her colleagues defined unnecessary GAS pharyngitis testing as testing in a patient with two or more viral symptoms (conjunctivitis, coryza, cough, diarrhea, hoarse voice, and viral exanthema), aged less than 3 years with no documentation of a household contact with GAS pharyngitis, absence of sore throat, or absence of examination findings expected in GAS pharyngitis cases.
The investigators illustrated a reduction in frequency of unnecessary testing from the monthly average of 64% to 41% using a P-chart, a type of graph used in statistical quality control to illustrate the proportion of defective or nonconforming values. They reported a significant reduction in unnecessary testing in children younger than 3 years from the pre- to postintervention period (P = .017).
Dr. Norton and her coauthors said they were aiming for a larger magnitude of improvement, which may have been in part because of cognitive bias. “Some providers reported fear of complications that could result from missed GAS pharyngitis diagnosis as a driver of their decision to perform GAS pharyngitis testing.”
There was no significant improvement in appropriate use of antibiotics for GAS pharyngitis from pre- to postintervention period, which Dr. Norton and her associates said points to a need for further research in other pediatric practices. “Adherence to guideline-based, first-line antibiotic selection was higher in this practice than reported in published national data, leaving little room for improvement.”
Dr. Norton and her coauthors had no relevant financial disclosures.

Relapsing scabies? Nails may hold a clue
cautioned Marie Chinazzo, MD, of Centre Hospitalier Régional et Universitaire Tours, France, and her associates.
Nails can harbor mites, representing a potential source for relapse, not only in children, but also in adults.
Few studies have addressed scabies on the nails, which is typically observed in immunocompromised adults with crusted scabies, but also rarely in healthy adults and children.
In an observational, multicenter, prospective study conducted between June 2015 and January 2017, 47 pediatric patients with common scabies, including 3 children under 2 years of age, presented with mites on the first toenail/thumbnail; two of them had already completed treatment and were experiencing relapse. All children with dermatologic diagnosis that was confirmed by visual inspection of “the delta sign” (presence of the mite seen as a triangle representing the head) using dermoscopy or by microscopic identification of Sarcoptes scabiei were included in the study. Dermatologists were required to complete a standardized questionnaire for each participant. Full body inspections and nail samplings also were done.
Clinical nail damage, consisting of hyperkeratosis, onycholysis, onychoschizia, and pachyonychia, appeared in 5 of the 47 patients (11%). No other cause of nail damage was determined in four of the cases, for which mites were not directly visualized, the researchers noted. The report was published in the Journal of Pediatrics.
Of the 47 confirmed cases, 26 were female; 23 were under 2 years of age; 20 were 2-12 years; and 4 were older than 12. Ten cases presented with significant medical history; none were classified as immunocompromised.
Fully 42 of the 47 children (89%) reported pruritus, and of these, 64% also had pruritus present in the family home; 60% of siblings and 45% of parents were affected.
None were diagnosed with crusted scabies. The mean delay from disease onset to diagnosis was 55 days. In 38% of cases, previous treatment for scabies had been rendered.
Treatments varied based on presentation. Ivermectin, esdepallethrin, and 40% urea were repeated after 10 days in at least one case. In another case, an entire family was treated once with topical 5% permethrin; once the child experienced relapse, oral ivermectin was employed. In the case of an 18-month-old girl with pruritus and skin lesions, topical corticosteroid was used for 10 days until such time that dermatoscopy revealed the “delta sign” and 5% topical permethrin was added.
The authors observed that nail scabies in the medical literature is more commonly seen in immunocompromised patients with crusted scabies and higher concentrations of parasites. They were able to locate only three other reports, all in adults, of nail scabies occurring with common scabies.
“Treatment of nail scabies is difficult and is not highly evidence based,” cautioned Dr. Chinazzo and her associates. The primary study limitations were the small patient population and that nail sampling was taken only from the first fingers and toes, which could mean that the number of mites present is actually underestimated, they added.
The authors had no relevant financial disclosures.

Additional training may be warranted for clinicians administering DTaP
Additional training may be needed for providers who administer DTaP vaccine to prevent errors in vaccination, but reported Pedro Moro, MD, MPH, of the Centers for Disease Control and Prevention’s National Center for Immunization and Respiratory Diseases and his associates in Pediatrics.
After Dr. Moro and his associates performed an automated analysis of all reports included in the Vaccine Adverse Event Reporting System (VAERS), which is coadministered by the CDC and the Food and Drug Administration, as well as a clinical review of reported deaths and a random sampling of serious reports in the database, they concluded that safety findings concerning DTaP were consistent with those from prelicensure trials and postlicensure studies.
DTaP vaccines, which included Infanrix, Daptacel, Pediarix, Kinrix, and Pentacel, were coadministered with one or more other vaccines in 43,984 (88%) of cases reported; of the reports included in the data mining, 5,627 (11%) were classified as serious, including 844 (2%) deaths. Of all reports received in the prelicensure clinical trials, injection site reactions and systemic reactions, such as fever and vomiting, were the most common reactions to DTaP vaccine.
In a 5% random sample of the 4,783 serious nondeath reports included in the study, 25% were neurologic, 23% gastrointestinal, and 20% were caused by general disorders and vaccine site conditions. Fully 80% of those flagged as neurologic were seizure related. In another 79%, for which intussusception was the most common gastrointestinal condition, all but two cases had rotavirus vaccine coadministered with DTaP. Altogether, there were 182 cases of anaphylaxis reported.
Serious events were characterized as death, life-threatening illness, hospitalization, lengthening of existing hospital stay, or permanent disability. In cases of death, reports that followed DTaP vaccine were manually reviewed by a physician, who evaluated autopsy report, death certificate, or medical records. The authors also included in their evaluation of records any reports of postvaccine anaphylaxis.
Of the 844 deaths, death certificates, autopsy reports, or medical records were obtained for 86%. Among these, sudden infant death syndrome (SIDS) was found to be the most frequent cause of death in 48%; of these, 62% were male infants, and 91% were infants under 6 months of age.
“It would not be uncommon to observe a coincidental close temporal relationship between vaccination and SIDS because this condition peaks at a time when children receive a relatively large number of recommended vaccinations,” said Dr. Moro and his associates. “There is a large body of evidence in which it is shown that vaccination is not causally associated with SIDS.”
The authors identified disproportional reporting for injection site reactions, as well as other events and conditions, to which they attribute, at least in part, administration of the wrong vaccine or formulation and administration at the wrong site. Such mistakes can be lessened or even prevented with provider education and training on appropriate recommendations and package insert specifications put forth by the CDC’s Advisory Committee on Immunization Practices, they advised.
While the authors praised VAERS for the wealth of timely data it has offered in detecting potential safety issues that may require further investigation, Dr. Moro cautioned that it is a passive surveillance system with limitations that warrant “careful interpretation of its findings.” Its purpose is to improve immunization programs.
Because it does not “meet the definition of research,” the work performed in this study was not subject to institutional review board evaluation and informed consent requirements, the authors added. VAERS generally is not able to assess whether vaccines are the direct cause of adverse events, primarily because of underreporting or overreporting, biased reporting, and inconsistency in quality and completeness of information reported. Because it does not tally number of vaccines administered, it is also unable to provide data needed to calculate incidence rates.
The authors had no relevant financial disclosures. The study was funded by the CDC and the FDA.

The Vaccine Adverse Event Reporting System offers confirmation that DTaP vaccines are safe and have a reasonably low frequency of adverse events. Despite this, the U.S.-based resurgence of pertussis shortly after acellular vaccines were introduced legitimately raised concerns over the efficacy of DTaP, which is now known to have a shorter duration of protection than its predecessor, the diphtheria, tetanus toxoids, whole-cell pertussis vaccine. Consequently, older children, adolescents, and adults are left unprotected without periodic booster doses, Flor M. Muñoz, MD, wrote in an editorial accompanying the study by Moro et al.
The World Health Organization’s recommendation to countries that never made the switch to DTaP is to continue using the whole-cell vaccines “because of their consistent higher efficacy” points to “an imperative need to develop more immunogenic pertussis vaccines that are also safe,” she observed.
“Active research is ongoing for the development of novel vaccines, including live attenuated vaccines, whole-cell vaccines with reduced endotoxin content to be less reactogenic, outer membrane vesicles–based vaccines, and acellular vaccine formulations prepared with new adjuvants or additional and novel antigens.
“As we go back to the drawing board in the fight against Bordetella pertussis, much work is needed to learn more about this fascinating pathogen and its interactions with humans to improve our understanding of how immunity and long-lasting protection can be achieved, to engineer and produce novel vaccines, and to design and perform the clinical studies that will eventually lead to the control of pertussis disease and its global impact with safe and effective vaccines for all,” Dr. Muñoz added.
Dr. Muñoz is affiliated with the section of infectious diseases in the department of pediatrics at Baylor College of Medicine and Texas Children’s Hospital, both in Houston. Her comments here were summarized from her editorial accompanying the article by Moro et al (Pediatrics. 2018. doi: 10.1542/peds.2018-1036).

“It would not be uncommon to observe a coincidental close temporal relationship between vaccination and SIDS because this condition peaks at a time when children receive a relatively large number of recommended vaccinations,” said Dr. Moro and his associates. “There is a large body of evidence in which it is shown that vaccination is not causally associated with SIDS.”
The authors identified disproportional reporting for injection site reactions, as well as other events and conditions, to which they attribute, at least in part, administration of the wrong vaccine or formulation and administration at the wrong site. Such mistakes can be lessened or even prevented with provider education and training on appropriate recommendations and package insert specifications put forth by the CDC’s Advisory Committee on Immunization Practices, they advised.
While the authors praised VAERS for the wealth of timely data it has offered in detecting potential safety issues that may require further investigation, Dr. Moro cautioned that it is a passive surveillance system with limitations that warrant “careful interpretation of its findings.” Its purpose is to improve immunization programs.
Because it does not “meet the definition of research,” the work performed in this study was not subject to institutional review board evaluation and informed consent requirements, the authors added. VAERS generally is not able to assess whether vaccines are the direct cause of adverse events, primarily because of underreporting or overreporting, biased reporting, and inconsistency in quality and completeness of information reported. Because it does not tally number of vaccines administered, it is also unable to provide data needed to calculate incidence rates.

Impact of varicella vaccination on herpes zoster is not what was expected
MALMO, SWEDEN – The unique 20-year U.S. experience with pediatric universal varicella vaccination hasn’t resulted in the anticipated increase in herpes zoster predicted by the exogenous boosting hypothesis, Lara J. Wolfson, PhD, reported at the annual meeting of the European Society for Paediatric Infectious Diseases.
In fact, the opposite has occurred. And this finding – based upon hard data – should be of considerable interest to European health officials who have been considering introducing universal varicella vaccination into their national health care systems but have refrained because of theoretical concerns raised by the venerable exogenous boosting hypothesis, noted Dr. Wolfson, director of outcomes research at the Merck Center for Observational and Real-World Evidence, Kenilworth, N.J.
The exogenous boosting hypothesis, which dates back to the mid-1960s, holds that reexposure to wild circulating varicella virus prevents development of herpes zoster later in life. Conversely, by vaccinating children against varicella, opportunities are diminished for reexposure to wild type virus among adults who weren’t vaccinated against varicella, so the hypothesis would predict an increase in the incidence of herpes zoster that should peak 15-35 years after introduction of universal varicella vaccination.
“The same virus that causes varicella in children later reactivates after going dormant in the dorsal root ganglia, and it reactivates as herpes zoster, which is 10 times more severe than chicken pox and leads to 10 times the health care costs. So if in fact implementing a universal varicella vaccine program would lead to an increased incidence of herpes zoster, this would be a bad thing,” the researcher explained.
However, the predictive models based upon the exogenous boosting hypothesis are built upon scanty data. And the models have great difficulty in adjusting for the changes in population dynamics that have occurred in the United States and Western Europe during the past quarter century: namely, declining birth rates coupled with survival to an older age.
Dr. Wolfson presented a retrospective study of deidentified administrative claims data from the MarketScan database covering roughly one-fifth of the U.S. population during 1991-2016. Her analysis broke down the annual incidence of varicella and herpes zoster in three eras: 1991-1995, which was the pre–varicella vaccination period; 1996-2006, when single-dose universal varicella vaccination of children was recommended; and 2007-2016, when two-dose vaccination became standard.
The first key study finding was that herpes zoster rates in the United States already were climbing across all age groups back in 1991-1995; that is, before introduction of universal varicella vaccination. Why? Probably because of those changes in population dynamics, although that’s speculative. The second key finding was that contrary to the exogenous boosting hypothesis prediction that the annual incidence of herpes zoster would accelerate after introduction of universal varicella vaccination, the rate of increase slowed, then plateaued during 2013-2016, most prominently in individuals aged 65 or older.
“In comparing the pre–universal varicella vaccination period to the one- or two-dose period or the total 20 years of vaccination, what we saw consistently across every age group is that herpes zoster is decelerating. There is actually less increase in the rate of herpes zoster than before varicella vaccination,” Dr. Wolfson said.
Uptake of the herpes zoster vaccine, introduced in the United States in 2008, was too low during the study years to account for this trend, she added.
Most dramatically, the incidence of herpes zoster among youths under age 18 years plummeted by 61.4%, from 88 per 100,000 person-years in 1991-1995 to 34 per 100,000 in 2016.
And of course, varicella disease has sharply declined in all age groups following the introduction of universal pediatric varicella vaccination, Dr. Wolfson observed.

Antipsychotics linked to increased body fat, insulin resistance in children
Twelve weeks of treatment with three different antipsychotics commonly used in children and adolescents with disruptive behavioral disorders was associated with rapid-onset adverse changes in adiposity and insulin sensitivity, results of a randomized clinical trial show.
The adverse effect on adiposity was greatest for children aged 6-18 years who received olanzapine, but was also seen in study participants randomized to receive risperidone or aripiprazole, according to results of the study published in JAMA Psychiatry.
These findings inform the risk-benefit analysis for off-label pediatric use of antipsychotics for disruptive behavior disorders, Ginger E. Nicol, MD, of Washington University, St. Louis, and colleagues wrote.
“The potential psychiatric benefits of antipsychotic use in this population, evident in this trial and others, should be carefully weighed against the potential for childhood onset of abdominal obesity and insulin resistance that – compared with adult onset – further increases long-term risk for [type 2 diabetes], cardiovascular disease, and related conditions,” the researchers wrote.
This randomized, prospective clinical trial included 144 antipsychotic-naive children and adolescents aged 6-18 years who had been diagnosed with one or more psychiatric disorders and clinically significant aggression. They were randomly and evenly assigned to 12 weeks of treatment with oral olanzapine, risperidone, or aripiprazole.
Those who received olanzapine had a 4.12% increase in percentage total body fat from baseline to week 12, as measured by dual-energy x-ray absorptiometry (DXA). That increase was significantly greater than the total body fat increases of 1.18% for risperidone and 1.66% for aripiprazole seen over that same time period (P less than .001 for time-by-treatment interaction), the researchers reported.
Insulin sensitivity decreased over time in the pooled study sample, with significant changes reported in insulin-stimulated glucose rate of disappearance, glucose rate of appearance, and glycerol rate of appearance. The changes did not differ significantly across the three treatment groups.
The lack of a placebo group in this study makes it unclear how much of the body fat and insulin sensitivity changes were attributable to antipsychotic medication. Psychiatric symptoms did improve significantly with treatment, the researchers noted.

The findings of this study by Nicol and colleagues corroborate previous reports that used conventional anthropometry to document the metabolic adverse effects of second-generation antipsychotic medications in children and adolescents, according to authors of an accompanying editorial.
The current study used “gold standard” methods of measurement to demonstrate that 12 weeks of treatment with low-dose olanzapine, risperidone, or aripiprazole led to rapid-onset changes in adiposity and insulin sensitivity, with larger increases in those who received olanzapine.
“As such, the study even more emphatically underlines the risks to which these vulnerable populations are exposed,” Marc De Hert, MD, PhD, and Johan Detraux wrote.
It is now is clear that the potential psychiatric benefits of off-label antipsychotics need to be weighed against the potential for childhood-onset obesity and insulin resistance, they added. However, longer-term studies that use hard end points, such as new-onset diabetes or cardiovascular disease are needed.

Summer colds
Enteroviruses cause most summer colds. The enteroviruses include echoviruses, coxsackieviruses, numbered enteroviruses, and the polioviruses. Most summer colds seen in private practice are self limited, presenting with fever alone or clinically distinctive pictures such as hand-foot-and-mouth disease (HFMD), herpangina, or pleurodynia. However, enteroviruses also cause serious illnesses such as meningitis, myocarditis, encephalitis, and neonatal sepsis. Enterovirus infections often are confused with bacterial infections and treated unnecessarily with antibiotics.
Enteroviral infections spread predominantly by the fecal-oral route. Contaminated swimming pools also may serve as a source of transmission. Enteroviruses colonize the respiratory and the gastrointestinal tract. The infection spreads to the lymph nodes, where the virus replicates and an initial viremia occurs on approximately the third postexposure day. The viremia results in subsequent spread to the throat (herpangina), and/or hands and feet (HFMD), lungs (pleurodynia), heart (myocarditis) or meninges (viral meningitis). Infection at the secondary sites corresponds to the onset of clinical symptoms 4-6 days after exposure. The clinical manifestations of enteroviral infections result from the damage caused by the virus at the secondary sites of infection.
Enterovirus pharyngitis starts abruptly and often is accompanied by fever. Younger children may present with increased drooling, hands in the mouth, and refusal to eat. Older children complain of sore throat as well as headache, myalgias, and malaise. Mild vomiting and diarrhea commonly accompany the respiratory symptoms. Herpangina is a specific syndrome of enterovirus pharyngitis; children with this syndrome have fever and characteristic papulovesicular lesions on the anterior tonsillar pillars, soft palate, uvula, tonsils, and pharyngeal wall. The lesions are discrete and average five per patient. They do not appear in the anterior part of the mouth.
Hand-foot-and-mouth disease is well recognized by clinicians who care for young children. The child presents with fever and papulovesicular lesions within the mouth that quickly become ulcerated and papulovesicular lesions on the palms and soles. The palms and soles often are puffy and red, and the child may act as though her hands and feet hurt, refusing to use her hands or walk. The fever accompanying herpangina and HFMD usually lasts 3 or 4 days, but fever that persists for a week is not uncommon. The pharyngitis follows a pattern similar to the fever.
Pleurodynia has a sudden onset of pain in the chest or upper abdomen. The pain appears to be muscular in origin; its intensity varies. It can be excruciatingly severe and accompanied by sweating and pallor. Older children describe the pain as sharp and stabbing. It occurs in spasms that can last for a few minutes to a few hours. During spasms, the patient has rapid, shallow respirations that suggest pneumonia. The symptoms usually last 1 or 2 days, but the illness can be biphasic, with symptoms resolving only to reappear a few days later.
Gastrointestinal manifestations are almost universal in enterovirus infections. The most common symptoms are anorexia, nausea, vomiting, and diarrhea. They usually are not severe and often occur in combination with other symptoms, such as fever and sore throat. Abdominal pain may be the only manifestation of infection; when severe, it can mimic appendicitis.
Enterovirus infections once were thought to be mild diseases that lasted 2-3 days. But a study of 380 children aged 4-18 years during July to October from private pediatric practices found that illness is prolonged in many patients (Pediatrics. 1998 Nov;102[5]:1126-34). The mean duration of illness was found to be 10 days for myalgia-malaise syndrome, 7 days for herpangina, and 7 days for HFMD.
Spread of enteroviral infections within a household was common. More than 50% of children studied had a family member with enterovirus illness. Half of siblings and 25% of adults within the household of the index case contracted an enteroviral infection. Some had the same presentation as the index patient, but it was not uncommon for other household members to have quite different presentations. For example, the first child seen might present with hand-foot-and-mouth disease, and a few days later a sibling might be brought for care with myalgia-malaise, and the parent might appear ill and complain of pleurodynia.
Summer colds can be costly to families. The duration of the illness and the multitude of nonspecific symptoms sometimes leads to concern about a possible bacterial cause, which prompts a diagnostic workup, including laboratory tests and empiric treatment with antibiotics. The direct costs vary with the syndrome; stomatitis and HFMD are the least expensive to treat because the clinical picture is diagnostic with a single office visit, but a severe manifestation such as aseptic meningitis are expensive to treat with associated emergency department visits, spinal tap, and sometimes hospitalization.

Herpangina is a specific syndrome of enterovirus pharyngitis; children with this syndrome have fever and characteristic papulovesicular lesions on the anterior tonsillar pillars, soft palate, uvula, tonsils, and pharyngeal wall. The lesions are discrete and average five per patient. They do not appear in the anterior part of the mouth.
Hand-foot-and-mouth disease is well recognized by clinicians who care for young children. The child presents with fever and papulovesicular lesions within the mouth that quickly become ulcerated and papulovesicular lesions on the palms and soles. The palms and soles often are puffy and red, and the child may act as though her hands and feet hurt, refusing to use her hands or walk. The fever accompanying herpangina and HFMD usually lasts 3 or 4 days, but fever that persists for a week is not uncommon. The pharyngitis follows a pattern similar to the fever.
Pleurodynia has a sudden onset of pain in the chest or upper abdomen. The pain appears to be muscular in origin; its intensity varies. It can be excruciatingly severe and accompanied by sweating and pallor. Older children describe the pain as sharp and stabbing. It occurs in spasms that can last for a few minutes to a few hours. During spasms, the patient has rapid, shallow respirations that suggest pneumonia. The symptoms usually last 1 or 2 days, but the illness can be biphasic, with symptoms resolving only to reappear a few days later.
Gastrointestinal manifestations are almost universal in enterovirus infections. The most common symptoms are anorexia, nausea, vomiting, and diarrhea. They usually are not severe and often occur in combination with other symptoms, such as fever and sore throat. Abdominal pain may be the only manifestation of infection; when severe, it can mimic appendicitis.
Enterovirus infections once were thought to be mild diseases that lasted 2-3 days. But a study of 380 children aged 4-18 years during July to October from private pediatric practices found that illness is prolonged in many patients (Pediatrics. 1998 Nov;102[5]:1126-34). The mean duration of illness was found to be 10 days for myalgia-malaise syndrome, 7 days for herpangina, and 7 days for HFMD.
Spread of enteroviral infections within a household was common. More than 50% of children studied had a family member with enterovirus illness. Half of siblings and 25% of adults within the household of the index case contracted an enteroviral infection. Some had the same presentation as the index patient, but it was not uncommon for other household members to have quite different presentations. For example, the first child seen might present with hand-foot-and-mouth disease, and a few days later a sibling might be brought for care with myalgia-malaise, and the parent might appear ill and complain of pleurodynia.
Summer colds can be costly to families. The duration of the illness and the multitude of nonspecific symptoms sometimes leads to concern about a possible bacterial cause, which prompts a diagnostic workup, including laboratory tests and empiric treatment with antibiotics. The direct costs vary with the syndrome; stomatitis and HFMD are the least expensive to treat because the clinical picture is diagnostic with a single office visit, but a severe manifestation such as aseptic meningitis are expensive to treat with associated emergency department visits, spinal tap, and sometimes hospitalization.

Enteroviruses cause most summer colds. The enteroviruses include echoviruses, coxsackieviruses, numbered enteroviruses, and the polioviruses. Most summer colds seen in private practice are self limited, presenting with fever alone or clinically distinctive pictures such as hand-foot-and-mouth disease (HFMD), herpangina, or pleurodynia. However, enteroviruses also cause serious illnesses such as meningitis, myocarditis, encephalitis, and neonatal sepsis. Enterovirus infections often are confused with bacterial infections and treated unnecessarily with antibiotics.
Enteroviral infections spread predominantly by the fecal-oral route. Contaminated swimming pools also may serve as a source of transmission. Enteroviruses colonize the respiratory and the gastrointestinal tract. The infection spreads to the lymph nodes, where the virus replicates and an initial viremia occurs on approximately the third postexposure day. The viremia results in subsequent spread to the throat (herpangina), and/or hands and feet (HFMD), lungs (pleurodynia), heart (myocarditis) or meninges (viral meningitis). Infection at the secondary sites corresponds to the onset of clinical symptoms 4-6 days after exposure. The clinical manifestations of enteroviral infections result from the damage caused by the virus at the secondary sites of infection.

How congenital heart disease affects brain development
Congenital heart disease (CHD) is the most common congenital anomaly, with an estimated incidence of 6-12 per 1,000 live births. It is also the congenital anomaly that most often leads to death or significant morbidity. Advances in surgical procedures and operating room care as well as specialized care in the ICU have led to significant improvements in survival over the past 10-20 years – even for the most complex cases of CHD. We now expect the majority of newborns with CHD not only to survive, but to grow up into adulthood.
The focus of clinical research has thus transitioned from survival to issues of long-term morbidity and outcomes, and the more recent literature has clearly shown us that children with CHD are at high risk of learning disabilities and other neurodevelopmental abnormalities. The prevalence of impairment rises with the complexity of CHD, from a prevalence of approximately 20% in mild CHD to as much as 75% in severe CHD. Almost all neonates and infants who undergo palliative surgical procedures have neurodevelopmental impairments.
The neurobehavioral “signature” of CHD includes cognitive defects (usually mild), short attention span, fine and gross motor delays, speech and language delays, visual motor integration, and executive function deficits. Executive function deficits and attention deficits are among the problems that often do not present in children until they reach middle school and beyond, when they are expected to learn more complicated material and handle more complex tasks. Long-term surveillance and care have thus become a major focus at our institution and others throughout the country.
At the same time, evidence has increased in the past 5-10 years that adverse neurodevelopmental outcomes in children with complex CHD may stem from genetic factors as well as compromise to the brain in utero because of altered blood flow, compromise at the time of delivery, and insults during and after corrective or palliative surgery. Surgical strategies and operating room teams have become significantly better at protecting the brain, and new research now is directed toward understanding the neurologic abnormalities that are present in newborns prior to surgical intervention.
Increasingly, researchers are now focused on looking at the in utero origins of brain impairments in children with CHD and trying to understand specific prenatal causes, mechanisms, and potentially modifiable factors. We’re asking what we can do during pregnancy to improve neurodevelopmental outcomes.
Impaired brain growth
The question of how CHD affects blood flow to the fetal brain is an important one. We found some time ago in a study using Doppler ultrasound that 44% of fetuses with CHD had blood flow abnormalities in the middle cerebral artery at some point in the late second or third trimester, suggesting that the blood vessels had dilated to allow more cerebral perfusion. This phenomenon, termed “brain sparing,” is believed to be an autoregulatory mechanism that occurs as a result of diminished oxygen delivery or inadequate blood flow to the brain (Pediatr Cardiol. 2003 Jan;24[5]:436-43).
Subsequent studies have similarly documented abnormal cerebral blood flow in fetuses with various types of congenital heart lesions. What is left to be determined is whether this autoregulatory mechanism is adequate to maintain perfusion in the presence of specific, high-risk CHD.
Abnormalities were more often seen in CHD with obstructed aortic flow, such as hypoplastic left heart syndrome (HLHS) in which the aorta is perfused retrograde through the fetal ductus arteriosus (Circulation. 2010 Jan 4;121:26-33).
Other fetal imaging studies have similarly demonstrated a progressive third-trimester decrease in both cortical gray and white matter and in gyrification (cortical folding) (Cereb Cortex. 2013;23:2932-43), as well as decreased cerebral oxygen delivery and consumption (Circulation. 2015;131:1313-23) in fetuses with severe CHD. It appears that the brain may start out normal in size, but in the third trimester, the accelerated metabolic demands that come with rapid growth and development are not sufficiently met by the fetal cardiovascular circulation in CHD.
In the newborn with CHD, preoperative brain imaging studies have demonstrated structural abnormalities suggesting delayed development (for example, microcephaly and a widened operculum), microstructural abnormalities suggesting abnormal myelination and neuroaxonal development, and lower brain maturity scores (a composite score that combines multiple factors, such as myelination and cortical in-folding, to represent “brain age”).
Moreover, some of the newborn brain imaging studies have correlated brain MRI findings with neonatal neurodevelopmental assessments. For instance, investigators found that full-term newborns with CHD had decreased gray matter brain volume and increased cerebrospinal fluid volume and that these impairments were associated with poor behavioral state regulation and poor visual orienting (J Pediatr. 2014;164:1121-7).
Interestingly, it has been found that the full-term baby with specific complex CHD, including newborns with single ventricle CHD or transposition of the great arteries, is more likely to have a brain maturity score that is equivalent to that of a baby born at 35 weeks’ gestation. This means that, in some infants with CHD, the brain has lagged in growth by about a month, resulting in a pattern of disturbed development and subsequent injury that is similar to that of premature infants.
It also means that infants with CHD and an immature brain are especially vulnerable to brain injury when open-heart surgery is needed. In short, we now appreciate that the brain in patients with CHD is likely more fragile than we previously thought – and that this fragility is prenatal in its origins.
Delivery room planning
Ideally, our goal is to find ways of changing the circulation in utero to improve cerebral oxygenation and blood flow, and, consequently, improve brain development and long-term neurocognitive function. Despite significant efforts in this area, we’re not there yet.
Examples of strategies that are being tested include catheter intervention to open the aortic valve in utero for fetuses with critical aortic stenosis. This procedure currently is being performed to try to prevent progression of the valve abnormality to HLHS, but it has not been determined whether the intervention affects cerebral blood flow. Maternal oxygen therapy has been shown to change cerebral blood flow in the short term for fetuses with HLHS, but its long-term use has not been studied. At the time of birth, to prevent injury in the potentially more fragile brain of the newborn with CHD, what we can do is to identify those fetuses who are more likely to be at risk for hypoxia low cardiac output and hemodynamic compromise in the delivery room, and plan for specialized delivery room and perinatal management beyond standard neonatal care.
Most newborns with CHD are assigned to Level 1; they have no predicted risk of compromise in the delivery room – or even in the first couple weeks of life – and can deliver at a local hospital with neonatal evaluation and then consult with the pediatric cardiologist. Defects include shunt lesions such as septal defects or mild valve abnormalities.
Patients assigned to Level 2 have minimal risk of compromise in the delivery room but are expected to require postnatal surgery, cardiac catheterization, or another procedure before going home. They can be stabilized by the neonatologist, usually with initiation of a prostaglandin infusion, before transfer to the cardiac center for the planned intervention. Defects include single ventricle CHD and severe Tetralogy of Fallot.
Fetuses assigned to Level 3 and Level 4 are expected to have hemodynamic instability at cord clamping, requiring immediate specialty care in the delivery room that is likely to include urgent cardiac catheterization or surgical intervention. These defects are rare and include diagnoses such as transposition of the great arteries, HLHS with a restrictive or closed foramen ovale, and CHD with associated heart failure and hydrops.
We have found that fetal echocardiography accurately predicts postnatal risk and the need for specialized delivery room care in newborns diagnosed in utero with CHD and that level-of-care protocols ensure safe delivery and optimize fetal outcomes (J Am Soc Echocardiogr. 2015;28:1339-49; Am J Cardiol. 2013;111:737-47).
Such delivery planning, which is coordinated between obstetric, neonatal, cardiology, and surgical services with specialty teams as needed (for example, cardiac intensive care, interventional cardiology, and cardiac surgery), is recommended in a 2014 AHA statement on the diagnosis and treatment of fetal cardiac disease. In recent years it has become the standard of care in many health systems (Circulation. 2014;129[21]:2183-242).
The effect of maternal stress on the in utero environment is also getting increased attention in pediatric cardiology. Alterations in neurocognitive development and fetal and child cardiovascular health are likely to be associated with maternal stress during pregnancy, and studies have shown that maternal stress is high with prenatal diagnoses of CHD. We have to ask: Is stress a modifiable risk factor? There must be ways in which we can do better with prenatal counseling and support after a fetal diagnosis of CHD.
Screening for CHD
Initiating strategies to improve neurodevelopmental outcomes in infants with CHD rests partly on identifying babies with CHD before birth through improved fetal cardiac screening. Research cited in the 2014 AHA statement indicates that nearly all women giving birth to babies with CHD in the United States have obstetric ultrasound examinations in the second or third trimesters, but that only about 30% of the fetuses are diagnosed prenatally.
Current indications for referral for a fetal echocardiogram – in addition to suspicion of a structural heart abnormality on obstetric ultrasound – include maternal factors, such as diabetes mellitus, that raise the risk of CHD above the baseline population risk for low-risk pregnancies.
Women with pregestational diabetes mellitus have a nearly fivefold increase in CHD, compared with the general population (3%-5%), and should be referred for fetal echocardiography. Women with gestational diabetes mellitus have no or minimally increased risk for fetal CHD, but it has been shown that there is an increased risk for cardiac hypertrophy – particularly late in gestation – if glycemic levels are poorly controlled. The 2014 AHA guidelines recommend that fetal echocardiographic evaluation be considered in those who have HbA1c levels greater than 6% in the second half of pregnancy.

In the newborn with CHD, preoperative brain imaging studies have demonstrated structural abnormalities suggesting delayed development (for example, microcephaly and a widened operculum), microstructural abnormalities suggesting abnormal myelination and neuroaxonal development, and lower brain maturity scores (a composite score that combines multiple factors, such as myelination and cortical in-folding, to represent “brain age”).
Moreover, some of the newborn brain imaging studies have correlated brain MRI findings with neonatal neurodevelopmental assessments. For instance, investigators found that full-term newborns with CHD had decreased gray matter brain volume and increased cerebrospinal fluid volume and that these impairments were associated with poor behavioral state regulation and poor visual orienting (J Pediatr. 2014;164:1121-7).
Interestingly, it has been found that the full-term baby with specific complex CHD, including newborns with single ventricle CHD or transposition of the great arteries, is more likely to have a brain maturity score that is equivalent to that of a baby born at 35 weeks’ gestation. This means that, in some infants with CHD, the brain has lagged in growth by about a month, resulting in a pattern of disturbed development and subsequent injury that is similar to that of premature infants.
It also means that infants with CHD and an immature brain are especially vulnerable to brain injury when open-heart surgery is needed. In short, we now appreciate that the brain in patients with CHD is likely more fragile than we previously thought – and that this fragility is prenatal in its origins.
Delivery room planning
Ideally, our goal is to find ways of changing the circulation in utero to improve cerebral oxygenation and blood flow, and, consequently, improve brain development and long-term neurocognitive function. Despite significant efforts in this area, we’re not there yet.
Examples of strategies that are being tested include catheter intervention to open the aortic valve in utero for fetuses with critical aortic stenosis. This procedure currently is being performed to try to prevent progression of the valve abnormality to HLHS, but it has not been determined whether the intervention affects cerebral blood flow. Maternal oxygen therapy has been shown to change cerebral blood flow in the short term for fetuses with HLHS, but its long-term use has not been studied. At the time of birth, to prevent injury in the potentially more fragile brain of the newborn with CHD, what we can do is to identify those fetuses who are more likely to be at risk for hypoxia low cardiac output and hemodynamic compromise in the delivery room, and plan for specialized delivery room and perinatal management beyond standard neonatal care.
Most newborns with CHD are assigned to Level 1; they have no predicted risk of compromise in the delivery room – or even in the first couple weeks of life – and can deliver at a local hospital with neonatal evaluation and then consult with the pediatric cardiologist. Defects include shunt lesions such as septal defects or mild valve abnormalities.
Patients assigned to Level 2 have minimal risk of compromise in the delivery room but are expected to require postnatal surgery, cardiac catheterization, or another procedure before going home. They can be stabilized by the neonatologist, usually with initiation of a prostaglandin infusion, before transfer to the cardiac center for the planned intervention. Defects include single ventricle CHD and severe Tetralogy of Fallot.
Fetuses assigned to Level 3 and Level 4 are expected to have hemodynamic instability at cord clamping, requiring immediate specialty care in the delivery room that is likely to include urgent cardiac catheterization or surgical intervention. These defects are rare and include diagnoses such as transposition of the great arteries, HLHS with a restrictive or closed foramen ovale, and CHD with associated heart failure and hydrops.
We have found that fetal echocardiography accurately predicts postnatal risk and the need for specialized delivery room care in newborns diagnosed in utero with CHD and that level-of-care protocols ensure safe delivery and optimize fetal outcomes (J Am Soc Echocardiogr. 2015;28:1339-49; Am J Cardiol. 2013;111:737-47).
Such delivery planning, which is coordinated between obstetric, neonatal, cardiology, and surgical services with specialty teams as needed (for example, cardiac intensive care, interventional cardiology, and cardiac surgery), is recommended in a 2014 AHA statement on the diagnosis and treatment of fetal cardiac disease. In recent years it has become the standard of care in many health systems (Circulation. 2014;129[21]:2183-242).
The effect of maternal stress on the in utero environment is also getting increased attention in pediatric cardiology. Alterations in neurocognitive development and fetal and child cardiovascular health are likely to be associated with maternal stress during pregnancy, and studies have shown that maternal stress is high with prenatal diagnoses of CHD. We have to ask: Is stress a modifiable risk factor? There must be ways in which we can do better with prenatal counseling and support after a fetal diagnosis of CHD.
Screening for CHD
Initiating strategies to improve neurodevelopmental outcomes in infants with CHD rests partly on identifying babies with CHD before birth through improved fetal cardiac screening. Research cited in the 2014 AHA statement indicates that nearly all women giving birth to babies with CHD in the United States have obstetric ultrasound examinations in the second or third trimesters, but that only about 30% of the fetuses are diagnosed prenatally.
Current indications for referral for a fetal echocardiogram – in addition to suspicion of a structural heart abnormality on obstetric ultrasound – include maternal factors, such as diabetes mellitus, that raise the risk of CHD above the baseline population risk for low-risk pregnancies.
Women with pregestational diabetes mellitus have a nearly fivefold increase in CHD, compared with the general population (3%-5%), and should be referred for fetal echocardiography. Women with gestational diabetes mellitus have no or minimally increased risk for fetal CHD, but it has been shown that there is an increased risk for cardiac hypertrophy – particularly late in gestation – if glycemic levels are poorly controlled. The 2014 AHA guidelines recommend that fetal echocardiographic evaluation be considered in those who have HbA1c levels greater than 6% in the second half of pregnancy.

Early diagnosis, treatment key to prevent permanent baldness in tinea capitis
and the substantially reduced overall quality of health, reported Aditya K. Gupta, MD, PhD, of Mediprobe Research and the University of Toronto, and his associates.
In a systematic review of both randomized, controlled trials and clinical trials published before June 1, 2017, the authors sought to identify differences between treatment medications and significant adverse side effects, and to evaluate the most effective methods for diagnosis. The study criteria included trials with clinical and mycologic diagnosis of tinea capitis, evaluation of efficacy rates and/or safety measures in participants aged 18 years or younger, yielded a total of 4,190 studies in this article published in Pediatric Dermatology.
Dr. Gupta and his colleagues evaluated efficacy rates that reported on mycologic cure (negative mycologic testing), clinical cure (complete absence of signs and symptoms), and complete cure (both mycologic and clinical cure). Trichophyton tonsurans was the most common organism reported in North America, and Wood’s light examination/light microscopic examination was the most common hair sample collection method identified.
In a population of 3,998 children who received treatment across all studies, five oral antifungals were used (terbinafine, griseofulvin, itraconazole, ketoconazole, and fluconazole). In addition, several studies examined the safety and effectiveness of combined oral and topical treatment in 833 children, while 25 children received topical-only therapy.
Although topical treatment may be useful adjunctively, some studies noted that oral treatment is necessary for effective resolution of tinea capitis. While some experts recommend continuing topical treatment until clinical and mycologic cure are achieved, the authors cautioned that “the presence of a topical antifungal in a culture media would likely lead to a false negative result, so a clinical confirmation is necessary.”
Adverse events
Altogether, 295 drug-related adverse effects were reported: 51.2% from terbinafine, 26.8% from griseofulvin, 12.2% from fluconazole, 8.5% from itraconazole, and 1.4% from ketoconazole; all were transient and mild to moderate in severity.
Of the total population observed, just 50 children (1.3% of 3,998) ceased treatment because of adverse effects of the medication.
Therapy choices
Of the 75 antifungal treatment combinations identified, cure rates were highest with continuous itraconazole and terbinafine (mycologic), griseofulvin and terbinafine (clinical), and griseofulvin and terbinafine (complete). Griseofulvin was more effective at treating Microsporum than Trichophyton infections, fluconazole was comparably effective in treating both Microsporum and Trichophyton infections, and continuous itraconazole and terbinafine were more effective at curing Trichophyton infections than Microsporum, noted Dr. Gupta and his associates.
Terbinafine treatment for Trichophyton infections was found to be effective at just 4 weeks, however, oral terbinafine was singularly responsible for more than half of adverse events reported. The authors suggested that this might be from its extensive biodistribution. In such cases, the authors recommended baseline monitoring of transaminase.
Although griseofulvin is the most widely prescribed medication for pediatric tinea capitis, primarily because of its cost effectiveness and accessibility, a 2016 Cochrane review found that newer treatments – terbinafine, itraconazole and fluconazole – offer comparative effectiveness in cases of Trichophyton infection. The relatively higher cost of these treatments and the prevalence of tinea capitis in lower socioeconomic populations, however, may render them impractical, the authors noted. As recent clinical trials have suggested significantly larger, weight-normalized doses are required in children to approximate the exposure estimates of adults, this should be of key consideration when choosing appropriate, cost-effective treatments.
Diagnostic issues
T. tonsurans cases of tinea capitis are most prevalent in North America, and recent data suggest they are on the rise. The organism typically infects human skin and hair, and can to survive for lengthy periods on inanimate objects, including combs, brushes, sheets, and blankets. Researchers credit the growing number of cases in North America to several factors. Infections from the fungus have become increasingly common in the United States and Canada as a consequence of changing travel and immigration patterns. In addition, many physicians still turn to fluorescence (Wood’s light examination) in diagnosing tinea capitis, but T. tonsurans does not show up with fluorescence and typically does not present with the classic black dots characteristic of other fungal species. As a result, many cases in North America are misdiagnosed as seborrhea, dandruff, and impetigo, and subsequently undertreated, leading to spread of the infection. It was noted that more than half of the included studies used some form of Wood’s light examination.
Of all the techniques addressed, microscopy was found to be the fastest, but not always the most accurate, means of diagnosing tinea capitis. Dr. Gupta and his associates advised that diagnosis confirmation and precise species identification is best obtained with cultured scrapings, but this process can take 3 weeks or longer.
While fomites and hair care practices play a key role in tinea capitis infection, large family size, crowded living conditions, and low socioeconomic status are predisposing factors. Those who come in contact with infected patients should be considered possible asymptomatic carriers and be evaluated accordingly for treatment and to prevent spread of infection, the authors advised. Furthermore, recent studies recognized the impracticality of isolating children recently treated with oral therapy from classrooms since shedding of spores can continue for months.
The researchers had no relevant financial disclosures to report.

Mircera approved for anemia in pediatric patients with CKD
Mircera®, methoxy polyethylene glycol-epoetin beta, was approved by the US Food and Drug Administration (FDA) to treat anemia in pediatric patients who have chronic kidney disease (CKD).
The drug is indicated for patients ages 5 to 17 years on hemodialysis who are switching from another erythropoiesis-stimulating agent (ESA) after their hemoglobin levels have stabilized.
The FDA also approved the agent to treat adult patients with CKD-associated anemia.
However, the drug is not approved to treat anemia caused by cancer chemotherapy.
The FDA based its approval on data from an open-label, multiple-dose, multicenter, dose-finding trial (NCT00717366).
Investigators enrolled 64 pediatric patients with CKD on hemodialysis. The patients had to have stable hemoglobin levels while receiving another ESA, such as epoetin alfa/beta or darbepoetin alfa.
Patients received Mircera intravenously once every 4 weeks for 20 weeks. Investigators adjusted the dosages, if necessary, after the first administration to maintain target hemoglobin levels.
Efficacy was based on the patients’ ability to maintain target hemoglobin levels and also on data extrapolated from trials of Mircera in adults with CKD.
Patients who received Mircera had a mean change in hemoglobin concentration from baseline of -0.15g/dL and 75% maintained hemoglobin values within ± 1g/dL of baseline.
Eighty-one percent maintained hemoglobin values within 10–12g/dL during the evaluation period.
The safety findings in pediatric patients were consistent with those previously reported in adults.
The most common adverse reactions occurring in 10% or more patients, as indicated in the prescribing information, are hypertension, diarrhea, and nasopharyngitis.
The drug carries a black box warning for increased risk of death, myocardial infarction, stroke, venous thromboembolism, thrombosis of vascular access, and tumor progression of recurrence.
Mircera is an erythropoietin receptor activator with greater activity in vivo as well as increased half-life, compared to erythropoietin.
